MACHINE FOR MAKING PAPER-BOX NEGKS.

, Application area-august is, 1924. Serial. No. 752,911;

To all 10.71.0721; it may concern i Be it known that I, GnARLEs H. OHLSSON,

a citizen ofthe United. States of America, residing at NewYork city, Bronx County, State of New York, have invented certain new and useful Improvements in Machines for Making Paper-Box Necks, of which the following is a specification. This invention relates to machines for making paperbox necks and in particular t a machine which partially covers the neckpiece with a paper binder and then forms and fastens the ends of the .same in position ready to be inserted into the box.-

An object of the invention i'sto provide a machine which will operate upon a plurality of blanks simultaneously .so that the same are completed and discharged from the machinein rapid succession.

A "further object of the invention is to provide a machine having few parts whereby the same will not clog up and hinder the efficient production of the paper box necks or inserts.

A still further obiect is to provide a machine in which the binder will be c0ntinuously' fed to the separate neck blanks so that the operation of the machine is continuous at the discharge end of the machine and in which the particular length of binder needed for each individual neck blank will be determined during the passage of the work through the machine.

I Referring to the drawings wherein I have shown a preferred embodiment of my invention V Figure 1 is a top plan view of a machine constructed in accordance with my idea, and shows the method of performing the various operations upon the product as the same progresses through the machine;

Referring to the drawings in detail 5 indicates the base plate of the machine which supports the standards 6 in which is jour' naled the main drive shaft 7 carrying at its outer end the gear 8 which is driven by a pinion 9 and its associated belt pulley 10. The shaft 7 carries intermediate its length a gear 11 from which is driven a train of gears 12, 13,14, 15, 16, 17. 18 and 19 (see Figure 2) the gears 13, 15 and 17 being aflixed to the ends of their respective disk shafts 20, 21 and 22 which are journaled in suitable bearing standards 23 supported on the base 5 and having extended portions 24 for the support of the work bed 25 along which the neck blanks travel. The

bearing standards also provide journals for .bed plate 25 is attached a blank holder 31 in the bottom of which is disposed a feeder 32 which comprises a notched bar adapted to "engage the end of the adjacent neck blank 33, the feeder being reciprocated through the medium of a forwardly extending bar 34 which is attached to one end of a'slide 35 located on the bed plate 5 the purpose o'f'which will be hereinafter described, the slide being operated by a bar 36 which is engaged by the lever 37.0perated through its journal-standard 38 by a cam arm 39 )vhich carries a cam roller 4:0,the latter engaging the cam 41 which is secured to the main drive, shaft 7 I L TA forward movement of the feeder 32 will, of course, remove the lowermost neck blank and carry it forwardly until it is caught between the first pair of feeding disks after. which it is fed along by the other sets of disks toward the discharge end of the machine. The finished neck has a smoothpaper back and edge binder 42, see Figure 6, which is fed into the machine in strip form as shown in Figure 2 where the roll 43 of material is held adjacent a glue pot 4a in which a roller operates to glue one side of the strip 42 as it comes off the roll. After it isgummed or glued, it travels to the intake end of the machine where it passes over suitable pulleys 45 to be introduced into the machine at a point just before-the first pair of rollers, or disks and directly beneath the neck blank which is fed into the disks as before described. During the travel of the blank and binder strip through the first pair of rollers the two are glued together and there remains an overlapping edge on the tape. After they pass under the auxiliary pressing roller 46, which is held in a support 477011 the work plate, they pass through a curling or folding device 48 which turns the overlappededge of the tape around the edge of the neck blank as indicated at 49' in Figures 6 and 7 after which the binder is cut by a suitable travelling knife 50 so that there is a small piece of the binder left extending over the end of the neck blank, this extended portion 51 being ultimately used to fasten the ends of the blank together when the same passes around the forming head to be later referred to. V

In that portion of the, machine where the knife is located the work bed is cut away I 1 as at 52 to allow reciprocation of the knife 50. This knife travels at "the'same speed ly as shown in Figure 6 to leave it extending out beyond the end of the neck blank to form a binding orconnecting flap. The knife is slidably mounted verticallyin a reciprocable upright- 53 which passes downwardly through the knife support 54;,

and through suitable slots in both the bot-, tom of the slide and bed plate 5. The upright 53 carries at its lower end the cam roller 55 which engages a grooved cam 56 fastened beneath the base plate 5. Upon a movement of the slide 35 towards the discharge end of the machine the knife will be carried therewith but its cam roller will travel through the lower groove of the cam 56 -(see Figures 8 and 9) to cause a downward movement of the knife blade 58 which will of course sever the binder between the ends of adjacent neck blanks. Upon the return movement, the roller will travel through the upper groove of the cam and keep the knife raised. Suitable adjustments ofthe knife may be made through medium of the set screws 59 and sliding saddles 60.

After the blank or neck has passed the knife it-iscarried forward by another set of disks mounted on the shaft 22, after which it is engaged by a hook 61 (see Figure 15) which moves one end of said blank into position beneath the forming head 62. The hook 61 is carried on a link 63 which is supported on a stub shaft 64 operated through the medium of a cam arm 65 carrying at its end the usual cam roller 66 which is operated by the cam 67 mounted on the shaft 22.

The forming head 62 revolves and as the blank is scored transversely as at 68 (see Figure 6) at which points it can be bent, it will, upon a revolving movement of the square forming-head 62 be bent into rectangular shape around the head, and the ex tended tab portion 51 which has been cut in the binding strip adjacent one end of the blank will hold the ends together to form the pompleted box neck as shown in Figure The forming head 62 is of course rectangular in shape and comprises an inner work receiver or carrier block 69 which has sliding engagement with the open end of the head 62 and is so arranged that, when a neck-piece which has been formed thereon and completed, a sliding movement of the head 62 over the block 69 will remove -;the neck and place it over an adj acentstati'onary receiving block 70 wherethe joined ends of the neck are firmly pressed together by a block 71 carried on the end of a lever 72 pivoted as at 73 relatively to the work bed plate, and having an extended cam arm 74 which engages a suitable cam 75, the latter of which causes operation of the block to press against the joined ends 76 of the formed neck piece periodically.

The mechanism for operating the head and its associated parts consists of a counter shaft 77 which carries at both ends the gears 78 and 73, the latter of which is toothed approximately three quarters of its circumference, the gear 78 being driven by the intermediate gear 19 which forms partof the gear train which operates the various disks and cams before referred to.

Mounted upon the base plate 5 is a standard 80 carrying in one portion 81 thereof the end of a through shaft 82 which carr es at its opposite extreme end the neck receiving block 70. Another portion 83 of the standard 80 carries the flanged end of a tubular shaft 84 which surrounds the shaft 82, and terminates in the neck carrier block 69. Surrounding the shaft 84: is still another tubular shaft 86 which at one end is flanged as at so that it can be held in revolvable relation with an upright 87 which is carr1ed on a slide 90 held in a suitable guide 89 which is affixed to the base 5 of the machine, in any suitable manner.

The shaft 86 carries at its opposite end, the forming head 62 which is hollow, and open at one end to receive the neck carrier block 69, the head 62 being slidable relatively thereto. The shaft 86 carries another :tubular shaft 88, the end of which is doubly flanged as at 91 between the flanges there bein disposed the ends of a forked lever 92 whic 1 is pivoted as at 93 to the shde and has an extended arm portion 94 which is engaged by a rock arm 95 (see Figure 1), soythat when the latter is operated it causes sliding movement of the shaft 88, which carries at its opposite end the disk 96 which operates a gripper arm 97 forminga part of a gripper mechanism that is embodied in the head 62, and to which reference will be made hereinafter.

The shaft 88 carries intermediate its ends the sleeved disk 98, the sleeve 99 of which passes through a standard 100 which is mounted upon the slide 90. The free end of the sleeve 99 carries a gear 101 which is operated by the aforementioned gear 79 as will be later described. The gear 79 and disk 98 abut against the opposite sides of the stand ard 100, and the disk 98 carries near its periphery a pin 102 whichpasses through the disk 96, head 62 and into block 69, the disk 96 being slidable on said pin. This pin is, of course, used to transmit a turning movement from the gear 101 to the head 62 and block 69, the head being also slidable on the pin.

The end of the slide 90 is engaged by a rod 103 which is connected through the medium of an extension 104, to a rock arm 105 which is carried on a suitable stub shaft 106 supported in a standard 107 and having disposed at its opposite end a cam arm 108 which is operated by a suitable cam 109 carried on the end of a shaft 110 which is operated from the main drive shaft 7 through the medium of bevel gears 111.

This shaft 110 also carries a cam 112 which operates a cam arm 113 carried on an adjacent shaft 114 which is mounted in suitable brackets and carries at its end the rock arm 95 hereinbefore referred to.

In order for the neck blank to be formed about the block 69 it is necessary that the end of the blank when moved into position beneath the block 69 be gipped firmly and held against one side of the block during a turning movement of the head 62 which forms the blank into a rectangle about the block 69. The gripper mechanism comprises, as before mentioned, a gripper arm 97 which is held against one side of the head 62 in a suitable grooved guide 115 and has an upturned portion 116 abutting against the sliding disk 96, a suit-able guide pin 117 being used through the disk and arm 97 to guide the latter. A coiled spring 118 surrounds the pin 117 between the head 62 and upturned portion 116 and tends to keep the arm 97 against the disk 96, so that when the disk has a movement relative to the head 62 there will be an opening or closing movement of the gripper, which consists of a gripper foot 119 pivoted as at 120 to the head 62 and adapted to contact with the carrier block 69 to hold the end of a neck blank in position while the block 69 is revolving to form the same. The foot 119 carries a contact arm 121 which engages the neck blank and holds it more securely. The foot is connected by a link 122 to the gripper arm 97, so that any movement of the latter will cause an opening or closing movement of the gripper foot 119.

In the operation of the machine, it will be noted that the blanks are fed in simultaneously with the binder and after the latter has been secured to the blank by its passage under the disks it is trimmed as before described by the reciprocating knife after which it is given an advance movement by the hook 61 (see Figure 15) so that the blank is fed to the head 62 or more properly to the forming block 69 where it is held by the gripper while the block is revolved. In order to prevent the blank from bulging outwardly during the revolving of the block I may provide on one side of the latter a. spring pressed roller 123 (see Figure 2) which is mounted on the end of a pivoted arm 12& and yieldingly contacts with the side of the block 69.

The arm 1% is somewhat resilient so that it will give way to the head 62 when the latter operates to remove the completed b-lank from the block 69. Another roller 124: is:

positioned beneath the underside of the block 69 on theendof a pivoted arm 125 held on .a standard 126, the .arm 125 being fastened to whereby the roller 12 1 is moved away fromtheblock 69 when'the head 69 hasia discharging movement, the'cam being shaped to provide a suitable movement at this time.

The head 62 of course is revolved through the medium of the gears 78, 7 9- and 101, the gear 7 9 being partly toothed to allow for a longitudinal movement of the head 62 and its associated parts.

In order to have the revolving movement of the head 62 arrested at the rightmoment I providea pivoted stop 131 which is operated through acam lever 132, stub shaft 133 and'operating arm 134 the latter of which engages the lower end of the stop 131 and causes its upper projected end 135 to enter a recess 136 in the disk 98 (see Figures 1, 2, 4 and 11). Q

The gear 79 is untoothed in one portion toallow a relative sliding movement of the gear 101 so that the latter is not revolved during said movement.

In the operation 'of the head it will be noted that the shaft 82 is fixed and carries the receiving head 70 while the shaft 84 carries the block '69 and revolves therewith, but has no: longitudinal movement The shaft 86 carried in the standard 87 of course has both revolving and sliding movement the latter being imparted by movements of the slide 90 through the medium oft-he rod 103 and its associated 'cam operated parts before described. This shaft 86 carries the head 62 so that any movement of said shaft is partaken of by the head. The slide is given one longitudinal movement for every revolution of the head 62, the movement occuring when the head 62 is stopped in its revolving movement, so that the neck blank formed on the block 69 (see Figure 11) is pushed off and onto the receiving head 7 0 from which it is removed by the next following neck blank and drops down the chute into a suitable container.

The shaft 88 is of course slidably and revolvably mounted and is revolved by reason of its being suitably keyed to the flange 99 of the disk 98 to which is attached the operating gear 101, the sliding movement being imparted by the lever 92 as before described so that the disk 96 is slid back and forth at the proper movement to open and close the gripper mechanism when a neck blank is fed to the forming block 69. The pin 102 is used to assist in the turning of the head 62 and to prevent revolvingmovement of the disk 96. The timing ofthe movements of the various shafts is carried out by the proper cut of the cams a detailed description of which is thought unnecessary.

It will be seen therefore, that I have provided a machine for making up paper box necks which will not only increase production but will eliminate waste and make a neater neck than has heretofore been possible n machines handling, each neck blank individually.

It is to be understood that my invention, in its broadest aspects, is not limited to the particular constructions shown, nor to any particular constructions or arrangements of parts by which it has been, or maybe, carried into effect, since many changes and alterations may be made in structures shown Without departing from the principles of the invention and without sacrificing its chief advantages. r
